Conditions

CVA stroke

Interventions

The experimental intervention is the manipulation of attentional focus when learning a balancing task. During practice, the internal focus group will receive instructions that direct their attention

Eligibility

Age

18 Years to 99 Years

Inclusion criteria

Inclusion criteria: - (First-ever & recurrent) stroke resulting in sub and/or supratentatorial brain damage - Receiving inpatient care in Heliomare - Time since stroke 2 - Able to stand independently for at least 1 minute - Able to understand instructions and cooperate with neuropsychological assessment (as judged by the patient*s neuropsychologist)

Exclusion criteria

Exclusion criteria: - No other neurological impairments - No orthopaedic impairments - No uncorrected hearing impairment

Design outcomes

Primary

Measure	Time frame
Balance task: The threshold rotational stiffness at which the patient successfully manages to keep the boards deviation below 2.5 degrees for 70% of the trial (RStiff2.5). Lower RStiff2.5 indicates better balance capacity. Automaticity: Sample entropy and fluency (jerk) of balance board movements. Higher sample entropy indicates less regular and hence more automatic movement execution, while lower jerk values indicate more fluent and hence more automatic movements. Cognitive dual-task performance (tone counting task): Accuracy (%) and reaction time (ms). To address a possible speed-accuracy trade-off, accuracy and reaction time are combined into a composite score: Performance = (Accuracy (%) / Reaction Time (ms)) x 100% Dual-task performance: Dual-task Costs (DTC) = (Dual-task performance - Single-task performance) / Single-task performance 100%	—

Secondary

Measure	Time frame
Cognitive functioning: Neuropsychological test scores will be expressed in standardised scores (z-scores) Tests of motor functioning, mobility, daily functioning/quality of life - Berg Balance Scale score (0-56) - Timed-up-and-Go score: time needed to complete test (in seconds) - Posturography: Amplitude of center-of-pressure (COP) & total path length of COP - 10 meter walk test: time needed to walk 10 meters (seconds) - FAC score (0-5) - USER - NSA (lower extremity: 0-80) Movement-Specific Reinvestment Scale (MSRS; 10-60) - Patients' inclination to consciously control their movements with an internal focus (Conscious Motor Processing subscale; 5-30) - Degree to which patients feel self-conscious about/monitor their style of moving (Movement Self-Consciousness subscale; 5-30)	—
